The correct answer is C. Please hand me the big, blue notebook.
Explanation:
In grammar, commas can be used to separate elements of the same kind, this also applies to adjectives that can be separated by commas if there are two or more adjectives that describe the same noun. In this case, it is recommended to use the comma only to separate adjectives but not before the first adjective or after the last one. According to this, the correct sentence is "Please hand me the big, blue notebook" because in this, the comma is used to separate the adjectives "big" and "blue" also, there are no unnecessary or incorrect commas.
